Abstract: Disclosed are systems and methods for implementing quantum-like gate operation using logical phi-bits of a quantum analogue system for achieving controllable classical entanglement. A method can include driving an array of elastically coupled acoustic waveguides using a first frequency and a second frequency different from the second frequency. A plurality of logical phi-bits can be determined based on acoustic field measurements associated with the waveguides. A tuning parameter value associated with a selected set of logical phi-bits can be determined, wherein the tuning parameter value is associated with a unitary transformation of a state of the selected set of logical phi-bits. A unitary gate operation can be implemented for the selected set of logical phi-bits by tuning an external driver coupled to a particular acoustic waveguide of the array by using the tuning parameter value to adjust one or more of the first frequency or the second frequency.

Abstract: Disclosed are systems and methods for scalable, large, multiple logical phi-bit quantum analogue system for achieving controllable classical entanglement (e.g., nonseparability). A method can include driving an array of elastically coupled acoustic waveguides by exciting at least a first acoustic waveguide of the array using a first frequency and a second acoustic waveguide of the array using a second frequency, wherein the first frequency is different from the second frequency. A plurality of acoustic fields propagating through the array of elastically coupled acoustic waveguides can be determined, each respective acoustic field generated based on the driving of the array using the first and second frequencies. A plurality of logical phi-bits can be determined based on spectrally partitioning the one or more acoustic fields, wherein each logical phi-bit of the plurality of logical phi-bits is associated with at least two independently measurable phases.
